Rmlh BL M36 H. HANSEN P 'T-WIRE STAPLE BENDER Filed June 4, 1955 H HH/mI mm In ATTORNEY Patented Mar. 31, 1936 UNITED STATES PATENT OFFICE 4 Claims.

This invention relates to clinching tools for wire clips and has for an object to provide a tool having a jaw provided with a V shaped opening to hold the wire clip against the flange and web of a T-fence post, there being curved prongs on the jaw forming a pivot upon which the tool may be swung to initially clinch one end of the clip over the flange of the post, the tool also having a pivoted hook jaw adapted to clinch the free end of the wire clip over the edge of the web of the post when the tool is swung on the prongs as a pivot.

v A further object is to provide a tool of this character having the hook jaw equipped with a projection and with a roller on the free end coacting with the projection in. clinching the wire J clip over the web of the post and directing the clip along opposite sides of the web so that the clip will be bent into tight gripping engagement with the post by the simple operation of pivotally swinging the tool upon the post.

A still further object is to provide a tool of this character which will be formed of a few, strong, simple and durable parts which will be inexpensive to manufacture and which will not easily get out of order.

With the above and other objects in view the invention consists of certain novel details of construction and combinations of parts hereinafter fully described and claimed, it being understood that various modifications may be resorted to within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawing forming part of this specification,

Figure l is a plan View of the tool in operative position on a T-fence post.

Figure 2 is a view similar to Figure 1 but showing the tool swung to complete the clinching operation.

Figure 3 is an edge elevation looking toward the right side of Figure 2.

Figure 4 is a detail cross section taken on the line 44 of Figure 2.

Figure 5 is a detail cross section taken on the line 5-5 of Figure 2.

Figure 6 is a detail cross section taken on the line 6-6 of Figure 1.

Figure '7 is a detail cross section taken on the line 1-1 of Figure 6.

Referring now to the drawing in which like characters of reference designate similar parts in the various views, the tool is shown to comprise a handle 10 terminating in a bifurcated jaw ll having a substantially V shaped opening [2'formed therein to receive a wire clip 13 of ordinary standard construction, and also to receive the flange l of a T-fence post [5. The branches of the bifurcation on one side of the 5 V shaped opening are provided with curved prongs 16 which hook over one edge of the flange l4 and form a pivot upon which the tool may be swung horizontally on the post. As best shown in Figure 3 one of the branches ll of the bi- 10 furcation on the opposite side of the opening [2,

is offset and this permits the fence wire 18 passing diagonally through the bifurcation in the jaw and this is best illustrated in Figure 6 wherein a groove 19 is shown which is formed in one wall 15 of the V shaped opening 12 to receive the fence wire 18. A diagonally extending groove 20 is also formed in the same wall of the V shaped opening and as best shown in Figure '7 this groove is of greater depth than the groove 19 and intersects 20 the groove 19 so that when the wire clip I3 is positioned in the groove 20 the clip will straddle the fence wire as best shown in Figure l. The wire clip receiving groove 20 also extends along the inner face of one of the curved prongs 16 as 25 best shown in Figure '7 so that when the tool 1s swung on the prongs as a pivot one end of the wire clip will be moved from the position shown in full lines to the position shown in dotted lines in Figure 1 and thus will be firmly clinched over 30 the edge of the flange 14 of the T-post.

A hook jaw 2| is pivotally secured to the jaw II between the branches I! by means of a pivot pin 22 and the jaw I l is recessed as shown at 23 to receive the pivoted end of the hook jaw. 35 The wall 24 of the recess forms a shoulder in rear of the pivot to engage the edge of the hook jaw and limit opening movement of the jaw to approximately the extent shown in Figure 1.

The hook jaw is provided in the free end or 40 bill with a bifurcation which provides branches 25 between which is rotatably mounted a roller 26 which is grooved to receive the clip and forms an abutment for bending the clip to clinch it 45 over the web 21 of the T-post when the tool is swung on the prongs as a pivot. A spring latch 28, best shown in Figure 4, is secured to one of the branches 25 by a screw 29 or similar fastener and the clip is initially placed with its free end 50 between the roller and the spring latch to properly position the clip in the jaws H and 2| for application to the post. The free end of the clip is releasably held by the spring latch since the latch is snapped back by the clip riding under- 55 neath the edge of the latch during the final stages of clinching the clip to the web of the post.

The hook jaw is provided on the inner face opposite the roller with a projection 30 and on opposite sides of the projection with wings 3| between which the clip is received during closing movement of the hook jaw. The projection 30 coacts with the roller 26 in clinching the clip over the edge of the web 2'! as best shown in Figure 2, in such manner that the clip is bent with its free end extending toward the initially clinched end of the clip.

In operation the wire clip I3 is inserted in the groove 20 and the tool is then applied to the fence post with the prongs l6 engaged over the edge of the post flange M. It will be here pointed out that the inner faces of the branches I! are arcuate in outline as shown at 3|, the radius of curvature being centered at the prongs l6 so that the handle l0 may be rocked horizontally from the position shown in Figure 1 to initially clinch the end of the clip carried by one of the prongs, to the flange M, the arcuate surfaces 30 of the branches l1 meanwhile riding upon the opposite edge of the flange and guiding the tool so that there will be no wobbling of the tool which might tend to displace the wire clip. The free hand of the operator may be used to initially start the hook jaw 2| so that the bill of the jaw passes the web 2'! of the post causing a slight bend in the free end of the clip as shown by dotted lines in Figure 1. Thereupon the handle It] may be swung in the direction shown by the arrow head in Figure 1 to the position shown in Figure 2, the pivoted hook jaw meanwhile advancing upon the web 21 and clinching the free end of the clip over the web.

From the above description it is thought that the construction and operation of my invention will be fully understood without further explanation.

What is claimed is:

1. A tool for clinching wire clips on T-fence posts comprising a handle terminating in a bifurcated jaw adapted to receive the fence wire, said jaw having a substantially V-shaped opening adapted to receive a wire clip and to receive the flange and the web of the T-post and dispose the wire clip against the flange and the web of the post, curved prongs on the jaw forming a pivot for the tool on the edge of the flange and adapted to clinch one end of the Wire clip over the edge of the flange, and a hook jaw pivoted on the first named jaw opposite the prongs and adapted to clinch the free end of the wire clip over the post web toward the clinched end of the clip when the tool is swung on the prongs as a pivot.

2. A tool for clinching wire clips on T-fence posts comprising a handle terminating in a bifurcated jaw having a substantially V-shaped opening adapted to receive a wire fence clip, the branches of the bifurcated end of the jaw receiving the fence wire between them, said branches at one end of the V-shaped opening terminating in curved prongs adapted to form a pivot for the tool on the flange of the T-post, said branches opposite the prongs being provided with curved faces defining one side of said V- shaped opening and having the center of the radius of curvature at said prongs whereby said faces may ride upon the flange of the post when the tool is swung on the prongs as a pivot, and a hook jaw pivoted between the last named branches and adapted to clinch the wire clip over the web of the post when the tool is pivotally swung on the prongs.
